CryptoWall, the New Security Threat


You have heard of CryptoLocker well now there is CryptoWall.  IT support service professionals are constantly keeping networks up-to-date and secure however this new version of CryptoWall has been released and it is beginning to infecting users at an alarming rate.

Crypto Malware – A Trojan horse that infects systems and holds data and systems hostage.

All Crypto malware is locking important files with a strong encryption.  When infested, you will see a pop-up window informing you that you have a set amount of time to pay for a key which will unlock the encryption. If you do not pay before the deadline, your files may be deleted.

CryptoLocker versus CryptoWall

CryptoWall, it is commonly found in zipped folders and PDF files sent over email. Most emails with the malware are disguised as invoices, bills and other business messages that we people are likely to open as they think it is safe.

CryptoWall can securely delete files.  The encryption has increased security which ensures the files are deleted. This leaves infected users two options: pay the ransom or retrieving the file from a backup, if available.

How do I protect from CryptoWall?

  • Do not open any suspicious attachments, period.
